Photorefraction-induced Bragg scattering in cryogenic lithium niobate ring resonators

Abstract

We report intracavity Bragg scattering induced by the photorefractive (PR) effect in high-$Q$ lithium niobate ring resonators at cryogenic temperatures. We show that when a cavity mode is strongly excited, the PR effect imprints a long-lived periodic space-charge field. This residual field in turn creates a refractive index modulation pattern that dramatically enhances the back scattering of an incoming probe light, and results in selective and reconfigurable mode splittings. This PR-induced Bragg scattering effect, despite being undesired for many applications, could be utilized to enable optically programmable photonic components.
